The aim of this commit is to change $g_show_user_email to a threshold
configuration item. This provides flexibility and consistency with other
similar configuration items.

• config_defaults_inc.php

  • Changed $g_show_user_email to $g_show_user_email_threshold

• constant_inc.php

  • Removed the ALL, NO_ANONYMOUS, and ADMIN_ONLY constants since the normal
    access levels will now be used to set the threshold.

• core/access_api.php
  (access_level_check_greater_or_equal): Do not return true for admin if access
  level is NOBODY. This special case of allowing admin to do everything has to
  be revised.
  (access_level_ge_no_default_for_private): Same as the previous method.

M core/obsolete.php

• Added $g_show_user_email. Note that currently the obsolete is not included
  anywhere. Julian will fix that.

M core/print_api.php
(get_email_link_with_subject): Updated to use $g_show_user_email_threshold.
(get_email_link): Updated to use $g_show_user_email_threshold.
